In your docker configuration file, you're not mapping the right port on those three services :
- node_exporter
- cadvisor
- karma-alert-dashboard
You need to map the ports that are exposed by those docker image.
For example, for the node_exporter, if you want to access it on port 9091 of your VM, you'll have something like this :
ports:
- 9091:9100 # node_exporter works on port 9100 by default
If you want to know wich port are exposed by those images, you can just have a look at the github documentation of each project or do a docker image inspect your_image
